We present observations of large-scale Rossby wave propagation in the mid-latitude South Pacific (25 ¿S) from analyzing 4 years of TOPEX/POSEIDON altimetry data. Using wavelet transform we separate phase propagation from amplitude modulation. The dominant Rossby wave has a wavelength of about 40¿ with a period close to 2 years (phase speed ~6.4 cm/s). Its amplitude modulates both interannually and intraannually. In addition, we also found a shorter-scale Rossby wave with a wavelength of about 16¿ and a period close to 9 months. ¿ 1998 American Geophysical Union
